PyCharm change file type association

问题:

I have a file in PyCharm and its used to be just a .txt file. Now I wanted to use .rst (reStructuredText).

I know that when I open a file without an ending for the first time PyCharm asks me what kind of file it is and how the syntax should therefore be interpreted.

Can i open up that dialog again somehow, or can I change the association in some other way?

回答1:

Actually, @CrazyCoder is right: If you accidentally mis-labeled the file, PyCharm remembers it and sets a "pattern" for the new file based on the name.

So go to Settings | Editor | File Types, find the type you accidentally mislabeled and remove it from the "Registered Patterns" list.

For example, I mislabed "osm.py" as text file, so under "Text files" I have:

*.bat
*.cgi
.
.
.
osm.py

Remove it and you get your py file colors back! You can also register a file association where there is no extension. By default this is associated as "Text file".

See Settings| Editor | File Types.

I was having the same problem and noticed that if I 'Invalidate Caches' under the File menu I was able to trigger a re-asking of the file type.

Definitely not ideal.
